# Physics: Must Pass

### I have to pass physics.

standing wave incident and reflected pulses are created with periodic frequency; appears stationary
node point with complete destructive interference (zero energy)
antinode largest amplitude; 1/2 way between nodes
infrasonic frequencies below 20 Hz
Ultrasonic frequencies above 20,000 Hz
Pitch measure of how high or low a sound is; frequency of sound wave
wave fronts 3-D distribution of waves (a sphere)
Plane waves seem like a straight line
timbre quality of tone resulting from the combination of harmonics present at different intensities (sound quality)
chromatic scale 12 note scale; 13th note is twice 1st notes frequency
beat periodic variation in amplitude of sound wave that is the superposition of two waves of slightly different frequencies
beat frequency difference in frequencies of two similar sound waves
amplitude max displacement from equilibrium
wave length distance between identical positions on consecutive waves
frequency number of waves passing a fixed point per unit time
period time required to complete a cycle
wave motion of a disturbance to a medium
medium matter through which wave travels
mechanical waves one that requires a medium to travel through
electromagnetic waves doesn't require a medium
pulse wave wave made of one traveling pulse
periodic wave wave made of periodic and continuing pulses
simple harmonic motion created by continuous pulses (periodic wave); follows rules for sine waves
transverse wave wave with vibration perpendicular to direction of wave's motion
longitudinal wave wave with vibration parallel to motion of wave (sound)
sympathetic vibrations vibration caused by resonance; starts vibrating because of the waves of second object
resonance phenomenon that occurs when the frequency of a force applied to a system matches the natural frequency of vibration of the system, resulting in a large amplitude of vibration
fundamental frequency lowest frequency of vibration of a standing wave; also called 1st harmonic
harmonics fundamental and successive multiples of the fundamental
intensity rate at which energy flows through a unit area perpendicular to direction of the waves motion
threshold of hearing 1000 Hz
Threshold of pain 1.0 W/M^2
relative intensity intensity of wave divided by intensity of threshold of hearing
decibel level measure of loudness
compression high density/peak
rarefaction low density/trough
wave speed distance traveled per time
damping amplitude of a wave diminishes over time due to energy loss
super-position combination of two overlapping waves
interference interaction of two waves
constructive interaction two waves add in same direction
destructive interaction two waves subtract due to a + and - amplitude
reflection interaction bouncing back of a wave at a boundary

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
